This is a bizarre one and any help will be greatly appreciated. I have a work laptop which has worked fine both at home, work and out and about for several years. About 2 weeks ago though, it stopped wirelessly connecting to the internet at home. All other devices at home are unaffected (which lead me to believe it was the computer). Wired works fine. Tried changing IPs, disabling firewalls etc...
Took the laptop into work and everything is fine. Now thinking it's the home connection somehow.
Done a factory reset on wireless router. Rebuilt the laptop. Totally clean on both. The problem still persists. It's just the one laptop on that specific connection when done over wireless.
For reference, it's not that there is no connection it's just that there is about 95% packet loss and when one does get through the time is about 3000ms. Have tried different channels and used scanners to check that the new channels are clear.
Any advice on where to go from here?
